UNITED STATES PATENT OFFICE JOSEPH R. BROWN, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE AUTOMATIC FIRE EXTINGUISHER COMPANY, OF NEW YORK, N. Y.

AUTOMATICQFIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent N 0. 278,217, dated May 22, 1883,

- Application filed February 21, 1888. (No model.)

To all whom it may concern Be it known that I, JOSEPH R. BROWN, of Bridgeport, in the county ot'Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Automatic Fire- Extinguishers; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to-the accompanying drawings, forming part of this specification.

This inventionhas reference to an improvement in what are known in the art of extinguishing fires automatically as sensitive automatic fire-extinguishers, in which the solder is used to hold the extinguisher closed, and is'placed away from the cooling effect of the water, so as to be readily acted upon by the heat from the fire.

The invention consists in the peculiar construction of the device, by which the release of the distributer will be more promptly effected,

as will be more fully set forth hereinafter.

Figure 1 is a view of a sensitive automatic fire-extinguisher. Fig. 2 is an end view of the same. Fig. 3 is a sectional view of the same, showing the same in action. Fig. 4 is a sectional view of a sensitive automatic fireextinguisher held against the internal pressure by two levers secured together by a fusible solder. Fig. 5 is an end view of the same. Fig. 6 is the distributer-disk.

In the drawings, a is the nipple by which the automatic fire-extinguisher is secured to the system of pipes.

11 is an enlargement of the case.

0 is a receptacle for the. distributer.

d is a conical valve formed on the end of the stem f.

c is a soft metal ring, which, with the valve (1, forms a water-tight joint by which the entrance of the water to the distributer is prevented.

g is the distributer-disk.

la is a ring made of any suitable slow-conducting material-such as paper, felt, cork, or any composition suitable for this purpose-a shoulder being formed on the case to retain the same, asis shown in Figs. 3 and 4:.

i, i are projections formed on the ring j, on which one end of the lever k is hinged or otherwise secured, the other end of the lever It solder, and to somewhat relieve the direct strain on the solder one of the levers is provided with the pin 1, which rests on the other lever. When the solder is sufliciently afl'ected 6 5 by heat the twolevers separate and the extinguisher is put instantly into operation.

- As the water cannot enter the device, and the soldered joint is far removed from the water, this kind of automaticfire'extinguisher c is very sensitive to the action of heat, and is put into operation before a fire can get any headway, even with the most inflammable material.

m is a test-tap by which any water can be drawn ott' that may have entered the device and the tightness of the valve ascertained.

I do not claim the use of the insulating-ring,

broadly, as this is shown and described in another application filed at even date with this.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In an automatic fireextinguisher, the combination, with the valve d, ring 6, constructed to exclude the water from the ex- 8 tinguisher, the stemf, the-distributer g, and the case arranged to receive the same, of the ring It and the lever k, constructed to hold the distributor until the same is released by the action of heat, as described. o

2. The combination, with an automatic fireextinguisher, ot' a ring having a non or slow conducting material interposed between the ring and distributer, and levers constructed to hold the automatic tire-extinguisher and re strain its action until released by the action of heat,as described.

JOSEPH R. BROWN.
